IMPROVEMENT IN SHlPPER-SADDLES.

Specification forming part of Letters Patent No. 121,792, dated December12, 1871.

To all whom it may concern:

Be it known that I, LLEWELLYN D. LoTHRoP, of Dover, of the county ofStrafford, of the State of New Hampshire, have made a new and usefulinvention having reference to the Shipper- Saddle or to such and thepinion-shaft thereof of a mowin g-machine; and do hereby declare thesame to be fully described in the following specification andrepresented in the accompanying drawing, of which- Figure 1 is a topView, Fig. 2 a longitudinal section, and Fig. 3 a transverse section ofmy improved shipper-saddle and spur-pinion, provided with clutch-teeth.Fig. 4 is a side view of the shipper-saddle as separate from thespur-pinion. Fig. 5 is a top view of the spur-pinion separate from thesaddle.

The invention is designed for use in the wellknown Spraguemowing-machine, and is for the purpose of remedying certain defects inthe operation of its shipper-saddle, as well as others incident to thearrangement of the oiling-induct of the spur-pinion. The shipper-saddleof the Sprague mower simply enters the upper part of the groove of thebody of the pinion; inconsequence of which it, by the leverage broughtto bear on it, soon becomes worn so as to cause the gear to do injury tothe operative lever, and also not to clutch to advantage.

In the drawing, A denotes my improved shipper-saddle, and B thespur-pinion with which it is used, such pinion being provided with aneck, 0, having a groove cut in and extending around it to receive thesaddle. My said improved shipper-saddle A is intended to extend entirelyaround in the groove, and is composed in part of two semicircularportions, to a, of an annulus hinged or pivoted together at or near oneend of each, and connected at their opposite ends by a screw, 1), goingthrough two ears, 0 0, extended from such ends, as shown. The uppertermini of such semicircular portions are connected to semi-cylindricaljoint pieces f f, which, when placed diametrically in contact, areconnected by the pivot 9 going through them, such joint pieces has beenan oilinghole arranged between two of its teeth, the oil for lubricatingthe bore of the pinion and the arbor thereof being poured into suchhole. To accomplish the process of lubricating'by such hole to advantagethe pinion had to be at rest, and consequently the machine had to bestopped in its operations to admit of such oiling being done. The oil,while the pinion was in revolution, would escape by the hole.

With my improvement, as described, the lubrication of the bore and thegroove of the spurpinion can be effected at one and the same time, andwithout the necessity of stopping the machine. For to do this I haveonly to pour oil into the oiling-hole of the head of the shipper. Suchoil after entering such head will flow into the frame of the neck, andwhen the hole i, while the pinion may be revolving, may come intocorrespondence with the oil-passage of the head, the oil will flow fromthe latter into the hole t, and thence upon the arbor. The shipper, byextending entirely around the neck or the groove thereof, will preventloss of oil from the holei while it may be in its lowest position orwhile revolving.

Thus with my improvement I not only render the operative parts lessliable to wear and more durable while in operation, but I am enabled toaccomplish the lubrication of the bore and groove of the spur-gear atone and the same time while the mowing-machine may be in action. I alsoprevent loss of oil, as stated.

There may be arranged in the bottom of the groove of the neck a narrowauxiliary groove to extend around such neck so as to more readily conveyoil from the induct h into the hole 1', especially while the spur-pinionmay be in revolution.

I claim- 1. The improved shipper-saddle, constructed substantially asdescribed, for use as set forth, viz.: as composed of the two separateparts, a, a, the joint pieces f f, the ears 0 0, connectingscrew 1),pivot g, and oil-passage h, all being arranged essentially as shown andexplained.

2. The improved shipper-saddle, arranged in the groove and to encompassthe neck, provided with the oiling-passage iarranged in such groove,substantially as described.
